Over the course of "Behind the Notes," we've learned that a nostalgic connection to comic books or skateboarding can bring in the notes on Tubmlr. This latest photo, taken by Bjørn Wad in Norway, has already amassed more than 20,000 notes, but it doesn't push any obvious cultural buttons. Still, this photograph of a woman lighting a cigarette off of a birthday candle has gone extremely viral. Although the woman wasn't actually celebrating her 100th birthday, I think it seems fair to say that the image captures something of the idea that, in Wad's words, "the elderly can also be rock 'n' roll." Assuming that the median Tumblr user is about 18 years old, maybe reblogging this image is a way for millenial youth to connect to older generations. This should be a joke, but maybe it isn't.
